Crate metrique_writer_core 

This crate contains core trait and struct definitions for metrique-writer, to allow for compatibility between (future) different major versions of metrique-writer. You should be using metrique-writer directly rather than this crate.

Modules

config

Contains configurations that are mostly useful for EMF-format metrics

entry

This module contains the Entry trait, which represents an entry that can be written to an EntryWriter in order to emit metrics

format

Contains the Format trait.

global

Contains the global_entry_sink macro, which can be used to define GlobalEntrySinks which are a rendezvous points between metric sources and metric sinks.

sample

Defines the SampledFormat trait, which allows for formats that can be sampled.

sink

Contains the EntrySink trait, which provides sinks into which metric entries can be written. Unlike EntryIoStream, these can be asynchronous.

stream

Contains the EntryIoStream trait, which writes entries to a destination synchronously.

unit

Contains utilities for attaching Units (such as percents, kilobytes, or seconds) to metrics. Conversion between different units is handled by Convert.

value

A Value is something that can be written to a given metric field.

Macros

global_entry_sink

Define a new global AttachGlobalEntrySink that can be referenced by type name in all threads.

Structs

ValidationError

An error type that describes why an crate::Entry isn’t valid. This can be because it violated general contracts (e.g. writing multiple values with the same name) or because it violated a format-specific contract (e.g. using a reserved property name).

ValidationErrorBuilder

Builder to record validation failures over time and bundle them into a single ValidationError Note that if no validation failures are added to the builder, ValidationErrorBuilder::build() will return None, which is useful to track if a side-effect produced any errors.
